Very hot weather can have implications for your health. As well as the usual symptoms of fatigue, it can also cause serious conditions (heatstroke, dehydration).

In old age, the body perspires less and consequently has difficulty maintaining a temperature of 37°. This can cause a rise in body temperature leading to a risk of heat stroke (hyperthermia, where the temperature rises above 40° and consciousness is impaired).

In children and adults, the body perspires a lot to maintain the correct temperature, but this leads to a loss of water, risking dehydration.

There are some simple steps you can take to help avoid problems, particularly at the beginning of a period of hot weather. It is important to prepare before you notice any signs that your body is suffering, even if these signs seem insignificant.

Protect yourself during the hottest hours of the day:

Avoid going out during the hottest hours of the day (11 am to 5 pm). Try, if possible, to take a siesta and relax in a cool place
